pitfall traps, species composition, abundance, trap efficiency


The article presents an analysis of the results of using a large number of pitfall trap lines to record the species composition of the two largest groups of phytophagous beetles (Coleoptera: Chrysomelidae and Curculionoidea) on the example of the territory of one region of the European part of Russia (the Republic of Mordovia). A series of collections were conducted between April and October 2022-2023, encompassing a diverse array of habitats (forest, steppe, near-water, wasteland) across various parts of the region. A total of 126 species from four families (approximately 18% of the fauna of the Republic of Mordovia) were recorded. These included 84 species of Curculionidae (22.9% of species), 42 species of Chrysomelidae (22.9%), 3 species of Brentidae, and 1 species of Anthribidae. Fourteen species are presented for the first time in the regional fauna. The collections are dominated by species whose adults are actively moving on soil or litter, particularly those belonging to the Alticini (Chrysomelidae) (33 species; 38.4% of the fauna composition) and the subfamily Entiminae (Curculionidae) (32 species; 45.1%). The collections represent a wide range of landscape-biotopic groups (meadow, ruderal, forest, near-water, and steppe species). Extensive materials obtained in pine forests and their pyrogenic successions in the Mordovia State Nature Reserve were also analyzed. The maximum species richness (30 species) was observed on fresh pyrogenic wastelands (1–2 years after fires). This is due to the association of many species of leafhoppers and weevils with habitats with sparse ruderal vegetation and coenophobic plants. A minimum of 10 species was observed on plots of old burned areas (13 years) where the primary vegetation is degraded and a full-fledged pine forest complex has not yet formed. The maximum abundance of two ecologically plastic species (Strophosoma capitatum and Hylobius abietis) associated with young undergrowth of pine and deciduous trees was recorded in this area.
